Hi Guys, I've put myself up for a number of weddings this season and I was wondering if I should use rechargable batteries over standards for reasons of economy. I'm carrying two SB 800's and will be shooting for 6 hours. Any thoughts?
Hi Chris. I believe the rechargables are better. I have a set of four ANS-MANN for my SB910 and no issues. But, I have had them less than a year and they are not used much. There seems to be a lot of information on the web about this. Among others, this link looks good.
I am using long time Sanyo eneloop AA HR6 (white ones, there are black one out, more power, less re-chrarging times, more expensive, wont use & wont recommend) for my SB800. They last long, very long. Even if I dont use my flash (I use it rarely) for a long time (weeks, even months) it looks like they are all time full. Nothing else. I believe they are the best.
Lion rechargeable batteries will produce a higher output voltage for a longer time than Alkaline batteries, energy density, but initially their output voltage could be lower than Alkaline batteries. Lion batteries keep a charge longer during storage, low internal resistance. When the Lion batteries run down the voltage drop is faster than Alkaline. The Lion batteries do not last as long a the Alkaline batteries and they require a special charger.
If you can afford it, I would look at the external power pack for the SB-800. With this pack you keep 4 batteries in the Speedlight to power the control circuits and the power pack will recharge the strobe light circuitry and provide a larger cache of power.
I've been using some Power2000 NiMh batteries from Adorama for about three years in my SB800. I have about four sets, and they give pretty good performance and life. At a six hour wedding last night, I only had to change out once, though I do have the extra battery add-on so it recycles a bit faster.
I saw the suggestion on the battery pack and am going to look into that.
Thanks guys, looks like I'll be ordering the re-chargables. BTW I have just got my kit together for shooting weddings. One D3X with a 24-70 f2.8 and a D700 with a 70-200 f2.8 both with SB 800 speedlights. Both held by a Black Rapid double harness.
Another vote for Eneloops. Thanks to my partner Bo, who gifted me with a couple of 4-packs, I switched to them for all my speedlights now. (I have three SB-800 with 5th battery and one SB-900). No more worries. As it has been mentioned, a MAHA charger is a must to keep them fresh and up to max charge, ready for long action.
I have Maha Immedions, low discharge NiMH - I think they are the same as the Eneloops. I get them from the same folks that have the C-9000 charger. I've been using them for at least 5 years now. The lower internal resistance is useful and they hold charge for what seems like forever. By now I have lost track of just how many I have, but certainly there are four in each of my six flash units, some AAAs are in my remotes, head lamp, and some other stuff, and they've now crept into all of my wireless keyboards, track pads, mice and the like. I probably have close to 50 of them now.
The new ones are 2400mah and should yield around 240 frames per set if you shoot at full power, maybe a bit more on an SB-800.
